Secure network architecture design using VLAN segmentation, firewall policies, and subnetting strategies for a small company, implemented in Packet Tracer with scalability and redundancy planning.

Secure and resilient network design for a government ministry with VLAN segmentation, firewall rules, redundancy, and Packet Tracer implementation for scalable infrastructure.

This is a comprehensive prototype project simulating a real-world, scalable IT environment tailored for an educational organization with hybrid operations. This project demonstrates strategic infrastructure planning, hybrid cloud integration, secure network segmentation, and practical deployment of both on-premises and cloud-based services.

Enterprise-level network simulation of a hotel setup with VLANs, RIP routing, DHCP, and inter-VLAN communication.

Multi-site network with IPsec VPN, Inter-VLAN routing, and centralized DNS/DHCP.

Design and implementation of a scalable Hospital LAN infrastructure using Cisco networking concepts, IP addressing, subnet communication, network topology planning, and cost analysis.

Designed and implemented a complete Hotel System network using Cisco Packet Tracer, simulating a real multi‑floor enterprise environment. This project demonstrates key CCNA‑level networking competencies including VLAN segmentation, inter‑VLAN routing, dynamic routing, DHCP, wireless access, security features, and device management.

Secure retail network architecture featuring VLAN segmentation, Extended ACLs for departmental isolation (HR/Staff), NAT Overload, and device hardening (SSH/VTY Access-Class).

Simulation d'une attaque IoT et mouvement latéral sur un réseau PME via Cisco Packet Tracer 9.0. Analyse de vulnérabilités (CWE) et remédiations (ACL, segmentation VLAN).

Designed and tested a multi-router IPv4 network in GNS3 using OSPF dynamic routing, DHCP address assignment, VLAN segmentation, subnetting, and ICMP connectivity testing. Network behaviour was verified through Cisco IOS routing tables, DHCP bindings, and Wireshark packet analysis of OSPF and ICMP traffic.

HSRP-Based Dual-Path Edge Redundancy and Segmented Access A complete Cisco Packet Tracer lab demonstrating HSRP gateway redundancy, Inter-VLAN routing, PAT/NAT configuration, and wireless client connectivity. Ensures high availability, secure VLAN segmentation, and resilient edge design using dual routers and Layer 3 switching.

Implementation of a secure enterprise network architecture using VLAN segmentation, Router-on-a-Stick, and Management Plane Protection (MPP) to enforce the Principle of Least Privilege.

A comprehensive network infrastructure design and simulation for a multi-floor hotel environment using Cisco Packet Tracer. Features segmented Inter-VLAN routing (Router-on-a-Stick), dynamic IP allocation via DHCP, and secured wireless access points.
